Control of Hand-Movements Towards a Target
Skilled performance of hand movements often requires a high level of accuracy. Discrete hand movements between a clear home position and a fixed target have been a preferred subject of numerous investigations (Howarth and Beggs 1981). Most studies of discrete movements have concentrated on the relationship between speed, distance, and accuracy. By contrast, very little work has been done on the manner in which skilled movements are executed in three-dimensional space. In particular, there are only a few data available which reveal the strategy which underlies free hand movements towards a target during the performance of a complex task (Soechting and Lacquiniti, 1981).
